SPINNING AND DOUBLING FRAME.

gPIECIFICATION forming part of Letters Patent No. 684,519, dated October15, 1901. Application filed November 27, 1899. Serial No. 738,396. (Nomodel.)

To all whom it may concern:

Be it known that I, ROBERT WIGHTON MON- CRIEFF, a subject of the Queenof Great Britain, residing at Newport Pagnel, in the county ofBuckingham, England, have invented a new and useful Improvement inSpinning and Doubling Frames, (for which I have obtained a patent inGreat Britain, No. 10,897, bearing date May 19, 1899,) of which thefollowing is a specification.

This invention relates to certain improvements in spinning and doublingframes, and refers particularly to such frames wherein in lieu of theordinary stationary ring and revolving traveler there is employed arotating ring held in vertical position centrically with the spinning ordoubling spindle by horizontal pulleys or runners fixed on revolvingvertical spindles, and has primarily for its object to provide meanswhereby the amount of drag for different counts of yarn may be regulatedor varied, as required, and to prevent over running of the rings, whichare pulled around by the yarn going onto the spindle-bobbin. Toaccomplish this, I make use of a ring constructed with a drag-flange inaddition to the holding-down flange or flanges, and I bring up or extendthe center spindle of one or more 'of the runner-pulleys, so as to allowof a sleeved weight-disk being placed loosely on it and pressing on thedrag-flange of the spinning or doubling ring. The amount of pres sure isthen regulated by annular weights of different thickness being placed ontop of the weight-disk, which weights are readily re moved therefromt Inorder that this invention may be fully understood, 1 will now proceed todescribe same with reference to the accompanying sheets of illustrativedrawings, upon which similar letters of reference indicate like parts ineach of the figures.

Figure 1 is an elevational View of a spindle fitted with a rotating ringwith one of its supporting pulleys or runners carrying thedragregulating device before referred to. Fig. 2 is an elevational Viewof the ordinary supporting pulley or runner. Fig. 3 is a diagrammaticplan view, to a smaller scale, showing several of the rotating rings andtheir supporting pulleys or runners; and Fig. at is an f is one of thesupporting-pulleys aforesaid,

which carries in accordance with this invention the drag-regulatingdevice now to be particularly described and which is particularlyillustrated in Figs. 1 and 2 of the drawings.

g is the center spindle revolving in the socket h and which is extendedupwardly sufficiently to allow of the sleeved weight-diske' beingcarried upon it. This diske' may when preferred be faced on its lowerside with leather or other similar or suitable material. The disk '5presses, as shown, upon the dragflange b of the rotating ring a.

is an annular weight (shown in section) which is placed upon and carriedby the weight disk i, and in accordance with the weight or weights soapplied is the amount of pressure varied or regulated to suit requirements. These weights are readily affixed and removed. The holding-downflange c of the ring a, comes up against the flange f of the hoodedpulley f, and as the spindles of the runner-pulleys are collared atbottom in the sockets the upward pull of the yarn is resisted by them,and there is consequently no upward pull on the weight-disk 2', whichrevolves with and is rotated by the ring a as it is revolved by the yarnZ going onto the spindlebobbin 6. The guide or hook for the yarn uponthe ring a is indicated by the letter W, the ring-rail by the letter at,and 0 indicates the driving-wharve.

p p, Figs. 2 and 3, are the ordinary hooded runner-pulleys, which act assupports to the rotating rings a.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In spinning and doubling frames, the rotating ring having adrag-flange and a holding-down flange, said flanges being arranged oneabove the other on the periphery of said rotating ring; the centerspindle provided with bearings in the ring-rail and extended upwardly;the supporting-pulleys contacting with the said flanges; and theweight-disk carried by the upwardly-extending parts of said centerspindle, substantially as specified.

2. In spinning and doubling frames, the combination of a ring rotatablymounted around the bobbin and provided with a dragfiange and aholding-down flange; with the center spindle having hearings in theringrail and being extended upwardly; and supporting-pulleys infrictional contact with said flanges; and the sleeved weight-diskcarried by the upwardly-extended parts of the center 15 spindle, saidWeight-disk bearing upon the said drag-flange, substantially asspecified.

In testimony whereof I affix my signature in presence of two witnesses.
